Patented Jan. 3, 1933 UNITE STATES EDWIN V7. TILTON, OF HAVEBHILL, MASSACHUSETTS, ASSIGNOR T LEJVIS L. COWAN, OF CINCINNATI, OHIO CUTTING, SOETTBTG, AND CQNVEYING DEVICE Application filed m a5, 19%. Serial. No. 470,644.

The invention relates to means adapted to out, sort and convey shoe soles.

Heretofore, considerable loss of time has been occasioned the operators of shoe sole cutting machines in collecting, sorting and packing the rights and lefts soles in boxes for shipment or storage. It has been customary for the operators of machines of this kind to manually collect and sort the right and left out soles from and around the machine, after which the soles are packed in boxes or containers for shipment.

The objects of the invention are to provide simple, eiiicient, economical, and durable means whereby rights and lefts shoe soles are adapted to be automatically sorted and conveyed from the cutting machine to packing boxes; and to provide means whereby the scrap material, or cat-tails, are automatically separated from the cut soles.

The invention consists in the combination of the elements, arrangement of the parts and in the details of the construction, as hereinafter claimed.

In the drawings:

Fig. 1 is a vertical transverse section of the invention;

Fig. 2 is a section taken on a line corresponding to 2-2 in Fig. 1;

Fig. 3 is a plan view of the invention;

Fig. 4 is a side elevational view of the invention;

Fig. 5 is a plan view of the invention, with parts removed;

Fig. 6 is a side elevational view of the invention.

The preferred construction of the invention, hereinafter described may be utilized in combination with any presently used shoe sole cutting machine of well known construction. In the drawings is shown one form of av usual shoe sole cutting machine 1 comprising the table 2 upon the horizontal apron or top 2 on which a strip of leather is placed previous to its being cut by the knives 3 and 4, respectively, to form the right and left shoe soles.

The knives 3 and 4, respectively, are fixed to the upper ends of the curved supports 5 and 6 having their lower ends 7 and 8 rotatably connected with the lugs 9 and 9 mounted in the upper edges of the sides 10 and 11 of the table 2.

Intermediate the front end 12 and the rear end 13 of the table, and secured to'the rear edge 16 of the apron 2, is the block 17 formed of wood, or other suitable material, received in the rectangular support 18 having its upper edge 19 suitably secured to the lower surface 20 of the top 2; The block 17 may have a groove, in its upper surface, into which the cutting edges 22 and 23 and thefknives 3 and 4 may be received, or when adjusted at a higher elevation the knives contact the lock without entering grooves.

Suitably jonrnaled in the vertical sides 10 and 11, of the table 2, is a horizontal shaft 24, which extends transversely of the table and has fixed to its end 25 the pulley 26 adapted to be rotated by suitable outside source of supply. Adjacent the pulley 26 is the usual clutch 27 receivable on the shaft 24 whereby the shaft 24 is adapted to be rotated or its movements stopped when the pulley 26 rotates continuously.

Beneath the shaft 24 are the spaced apart horizontal shafts 28 and Y29 having their outer ends suitably j ournaled in the sides 10 and 11 of the table 2. Suitably fixed to the shaft 24 is the pinion gear 30-which meshes with the gear 31 suitably fixed to the shaft 28. Adjacent the gear 31 is the gear 32, fixed to the shaft 28 meshing with the gear 33 suitably fixed to the shaft 29. On the outer protruding ends 34 of the shafts 28 and 29 are the cranks 35 having fixed thereto the upwardly extending connecting rods 36 having their upper ends 37 rotatably connected with the lugs 38 extending horizontally and outwardly from the upper ends of the arms 5 and 6 whereby rotatable movement of the shaft 24 is adapted to cause the knives 3 and 4 to move alternatively from the position shown in Fig. 6 downwardly with their cutt ng edges 22 and 23 receivable on the block 17. The cranks 35, on the shaft 28 are advanced, with respect to the cranks 35 on the shaft 29 whereby the cutting edge 22 of the knife 3 is adapted to contact the block 17 adjacent the grooves 21, and recede therefrom a short period of time before the cutting edge 23 of the knife 4 contacts the block.

Rotatably mounted in the upper edges of the sides and 11, of the table, is the horizontal shaft 39 having suitably fixed thereto the spaced apart receiving wheels 40 and 41 each comprising a plurality of equal distance spaced apart plates 42 having their inner edges suitably fixed to the hub 43 which is fixed to the shaft 39. The wheels 40 and 41 are arranged adjacent the block 17 and are positioned so that the space 44, between the outer edges of the plates 42 and the rear side of the block 17, permits the scrap material, or cat-tails, to drop on the floor, or in a receptacle which may be suitably fixed to the sides of the table.

Fixed to the outer end 45 of the shaft 39 is the ratchet connection 46 with the upper o end 47 of the connecting rod 48 having its lower end connected with the crank 49 fixed to the outer protruding end 50 of the shaft 24 whereby, during operation of the ma- .chine, the wheels 40 and 41 intermittently from the leather strip, since the cutting edges of the knives are properly formed to accomplish this result. After the knives have cut the soles from the strip and have begun their upward movement, and the wheels 40 and 41 are in stationary position the operator slides or moves the leather strip toward the rear of the table whereby the soles are moved -be tween the plates 42 on the wheels. The scrap material falls between the outer edge 44 of the plate and the block 17. Further movement of the arms 5 and 6, through operation of the mechanism previously described causes the wheels 40 and 41 to rotate in the direction indicated by the arrow 51 whereby successive movements of the knives, and the operator forcing the leather strip toward the rear of the table, causes the soles, forced between the plates 42, to drop from the wheel into the respective inclined chutes 52 and 53 fixed to the upper ends of the rods 54 and 55 having their lower ends connected with the pins 56 and 57 and the links 56' and 57' connected with the lower ends of t ie connecting rods 36 and 37 whereby the movement of the chutes is regulated to cause the right hand soles to fall into chute 52 and the left hand soles to fall into chute 53 from the wheels 40 and 41. The soles slide downwardly of the chutes andfall therefrom into suit-able receptacles placed thereunder. The rocking action of the connecting rods 54 and 55 are timed to cause the chutes to move toward and away from the wheels 40 and 41 so that the chute 52 is positioned to catch the right sole when it drops and the chute 53 is properly positioned to catch the left sole when it drops.

An advantage of the invention is that the soles, as cut from the leather strip, are automatically conveyed from the machine 1 into the packing or shipping boxes 52' and 53 which are positioned beneath the chutes or troughs 52 and 53, without the necessity of being touched or handled by human agency, whereby the the labor cost usually associated with cutting and packing shoe soles is importantly reduced.

It is therefore a 3parent that I have invented a highly desirable device of the character described which may be utilized with various kinds of shoe sole cutting machines by modification of the means by which the wheels 40 and 41 are operated in accordance with the particular construction of the machines with which the invention is utilized.

My device may be made of any size, and constructed of any materials deemed convenient and suitable for a device of this character, and while I have illustrated and described a form of construction and arrangement of parts found desirable in materializing the invention, I wish to emphasize the fact that I desire to include in this-application all mechanical equivalents and substitutes that may fairly be considered to come within the scope and purview of the invention as defined in the appended claims.
